Hee haw—and hang on, at least if you head to the upper stretches of this trail! One of Texas’s favorite places to cool off, this river has lazy tuber-relaxing downstream, but kayak buffs love to ramble along its upper quadrants, above Canyon Lake, on the 9.9-mile Nichol’s Landing Paddling trail. Stunningly beautiful, the river here undulates below high limestone bluffs, marked by cypress, wildflowers, and rocky bits of soil. With terroir as rolling and green as Tuscany, the Guadalupe corridor gets the summertime party started. With sailing, fishing, boating, and tubing, the U.S. Corps of Engineers-built Canyon Lake gives "playground" a whole new meaning.
